A benefit of 3D Modeling is the use of the design data to analyze the physical strength, thermal or fluidic properties of your design before building anything.  

Two methods of Finite Element Analysis are used by WinTech Design to analyze design structures. The first is the embedded Analysis Engine in Solidworks (CosmosExpress). The second is Structural, Thermal and Computation Fluid Dynamic modeling available through our associate Predictive Engineering, Inc. http://www.predictiveengineering.com/  Call 541-754-1438 for more information.
